GRQUNDING DEVICE.

Peieniee lFob 2e iiiiig 1 Application filed December 1 1911. Serial No.eemei. M Elli To all whom it may concern Be it known nth-it I, HENRY E.SCHIMMEL, :1 citizen of the United States, residing at Providence, inthe rounty of Providence and State of Rhode Island, have invented.certain new and useful Improvements in Grounding Devices, of which thefolli'iwing is a specification.

Myinventicn rel iites to grounding devices and more particularly to themeans for con meeting an insulaiiug head to an electrical conduit.

Theobject of my invention is to alioixl a practical and appi'oviiblemeans for grounding ll wllfi as 21 substitute for the employment of ehuehing heretofore required to he soldered to the end of a conduit,which bush lug has proved very unsatisfactory in operatiom and effect asWell as involving much labor in applying.

The further object of my invention is to render the coupling memberreadily applicable to use in conjunction with an approved ill 3,e'sect'ion on line i; i) of form of insulating heed poition; illld filltherto piovioe ii structure which 13 simple to operate, effective inuse, and inexpensive to manufacture,

To all" the above enumeinted ends essentially my invention consists insuch parts and in such combinations of parts as fall Within the scope ofthe appended claim.

In the acconi anying drawings which form a part of tliis specification,Figure 1 is a front elevation oi my grounding device, Fig. 2, e sideelevation of some, Fig.

Rig. 2, Fl -54,11 section on line 20 w of Fig. 2, 5, a side ele vziliionof the coupling iiie ubei', Fig". (L a plan View of the some, 11ml Fig.i, :1 section on line ma." of Fig. 6. i

Like reference characters indicate like A parts, throughout the views.

In the accompanying drawings, 1 represents a pipe or comhiit provided atone end with the usual threads 2, which engage the interior threads 3 ofan extension coupling 4, upon vhose body portion 5 and integraltherewith is an integral transversely ilisposed SQZRLClI'CHlZMlLlQ 6provided Wit-l1 a longitudinal opening "I. The port-ions 6 midi i areadapted to form e seat or socket for a grounding wire 8. The body 5 ofthe cou pling lies a polygonal exierior, and 6Xi2fi(i 121g from the bodyportion in ulmemenla iLllQlQWillll is ii tubular portion 10, pi ovirleclwith external threads 11. These thread are adapted to engage internalthreads 12- upen the neck 13 of l'he enlarged body por" tion 1% oi onmenial-mg head, which head is completecl by the insulating plate 15.

The plate 15' is provided with a plurality grounded iii 2:2 which may bea gas pipe or Water pipe. iihmneciing the Wire 8 and the 'ueuii-iil wire18 is ii eonueceing wire 23.

What claim is;-

A. llPiHl and conduit iclupteii to carry cur- :s-eutwires uxul :1neutral. wire, a, coupling llfiil/PiELi to connect said head andconduit, said heacl carrying an insulating plate with 21 plurality of iii(iepen(lent openings for the neutral and current wires, a transverselycliepoeeii lug integral with the interior of said coupling and providedwith :1 longitudinal opening adapted to receive a girouucl lug wire. {lgrounding Wire entering the opening in said lug, current wires ill81S-lllffi .lho hemi, the conduit and the coupling and said plate .2.neutral wire hovel-sing the hemLlhe oouiluit tlllll he coupling and soldplate il'ili'i e iviie conneeling said grounding Wire llilfi iheiieuti'ul wire.

in tesszimoiiy whereof I have affixed my signature in presence of twoWitnesses.
